Enum TaskMutationOutcome 

pub enum TaskMutationOutcome {
    Committed {
        fence: FenceToken,
        advisory: AdvisoryOwnership,
    },
    StaleLocalVersion {
        current: FenceToken,
    },
}

Outcome of a task-list mutation (claim or complete).

Returned by TaskListHandle::claim_task_versioned and TaskListHandle::complete_task_versioned.

Committed means the mutation was applied to the local replica and a delta was best-effort published — it does NOT mean any peer has observed the change, and it does NOT grant exclusive ownership. Claims and completions are advisory: concurrent operations on other replicas coexist in the CRDT and resolve to a single deterministic winner (earliest timestamp, then lexicographic agent id) only after convergence.

StaleLocalVersion means the caller’s fence token did not match this replica’s current (epoch, revision) — a LOCAL fencing signal. It is NOT a distributed conflict: two replicas at the same token both pass, so the fence cannot provide cross-replica exclusion. A mismatch may be a stale revision (the local snapshot moved) OR a stale epoch (the daemon restarted and the caller’s token predates it — the restart-ABA case).

Variants

Committed

The mutation was committed locally; fence is the new local token.

Fields

fence: FenceToken

The task list’s fence token after this mutation (epoch + revision).

advisory: AdvisoryOwnership

Advisory ownership snapshot computed from the local OR-Set at commit time. Advisory — see AdvisoryOwnership.

StaleLocalVersion

The caller’s fence token did not match this replica’s current token; nothing was mutated. Local staleness guard (stale revision) or a restart-epoch mismatch — never a distributed conflict.

Fields

current: FenceToken

The task list’s current (unchanged) local fence token.
